CLASP.

To all whom 'it may concern:

Be it known that I, ALvAH O. BoYLANn, a citizen of the United States, and a resident of Aurora, in the county of Hamilton and 5 State of Nebraska, have invented certain new and useful Improvements in Clasps,.of which the following is a specification.

This invention is an im rovement in clasps for clasping fabrics andp the like; and the invention consists in certain novel con structions and combinations of parts as will be hereinafter described and claimed.

In the drawings, Figure 1 is a perspective view of a clas embodying my invention with the pivote jaw closed. Fi 2 is a side view of a clasp with the pivote jaw closed in full lines, and the spring tongue of said jaw in dotted 'lines in position to release the jaw, so the latter may be raised. Fig. 3 is a side view of a clasp showing the pivoted jaw raised. Fig. 4 a cross sectional view through the pivoted arms of the jaw, and showing sucharns projecting below the up er face of the base plate, and Fig. 5 is a etail View illustrating the rocking spur, and Fi 6 is a detail section on about line 6-6 o Fig. 5.

In carrying out my invention I provide a main or ase plate A upon which is mounted a post B. t the ends of the said post, the base plate is provided with slots or recesses A to receive the ends of the arms of the pivoted jaw. At the base of the post B I provide lateral studs C, to which are pivoted the arms. D of the jaw D, the said arms bein deflected downwardly from the body of t e jaw and provided with openings A. The arms D are extended at D2 into the o enings A in the plate A, thus preventing tlie arms from being accidentally forced 0H the pivoted studs in the useof the invention. The body of the jaw D is in the form of a plate, and it is provided with a tongue D12 extending longitudinally of the jaw and havingits rear end D13 or end adjacent the pivot of the 'aw,'arranged when the jaw is closed to a ut the front side of the ost B, and so hold the jaw closed, and t e front end of the tongue is arran ed to be depressed to elevate its rear end cear of the post when it is desired to release'the jaw. In carrying out this f e'ature of my invention the tongue has a yield- Specification of Letters Patent;

ing connection between its ends with the. body of the jaw so it can be rocked pivotally to elevate its rear end or depress its front end, and in constructing Vthe jaw I prefer to form the tongue by a front incision Da which sepa-rates the front end of the tongue from the body of the plate and by rear inthe tongue from the body of the jaw to permit the pivotal movement of the ton ue as desired. This operation of the pivotedwith means for en agement 'with the fat.

ric or other materia to be held b'y the clasp. This is preferably a s ur E, and I also prefer to support the sai spur' at the front end of the tongue D12, and to pivot it as shown, so it may be rocked-between its different positions. In carrying out this feature of my invention thefrontend; of the tongue is notched at D, and the spur is pivoted at E within the saidnotch, and has a point or projection ,E2 which may engage the fabric to hold the same when it is deslred, and the spur may be rocked to release its point or projection from the fabric,and the front end of the tongue be then depressed to free its rear endfrom the post in order to open the jaw.

It will 'be noticed that the spring tongue of the jaw o erates to lock the Jaw 1n closed position, an also to give resiliency of the yielding action of the said jaw. At the same time when the jaw is open the spring tongue is entirely free and there is no spring actionon the jaw especially when the jaw is in the full open osition shown in Fi 3.

It will be noticed that the pivot stu s C are above the plane ofthe plate A, and that the arms D of the jaw pivot on said studs and have extensions beyond the studs which projectk into .the recesses A in the main plate. It will be noticed that the ivot studs are approximately in line with t e post B, so that the rear end of the spring tongue -cisions D11 which separate the rear end of ma be moved across the upper end of the enga ing in curing the jaw in sai positions.

The rocking stud E, it will be noticed from Fig. 2, operates to lift the front end of the spring tongue and so adjust the rear end of said4 tongue downwardl to bear. 1n front of the post B, the stud opxeratmg in this way as a movable device at t e front end -of the tongue for elevating the said end and holding the rear end of the tongue in en agement with the post, the said movable evlce thus coperating with the spring tongue and the post in the operation before described.

I claim--l 1. A device substantially as described, comprising a main plate, having recesses and pivot studs adjacent to and above the recesses in the main plate, and a jaw having depending arms projectin at their extremities into the lrecesses 'o the main plate, and provided with openings receiving the pivot studs. j

2. A button or clasp having a main plate, a post thereon, and a jaw (pivoted below the upper end of said post an having a tongue front of said post for securing the jaw in closed in opening and closing the jaw..

3. The combination of a main plate, a post a jaw pivoted at its rear end. adjacent to the post, and a ton e extending ongitudinally .of the-'jaw an .arranged at the post for sethereon,

4. A clasp comprising a main plate, a ost thereon, and a'pivoted jaw having a ongitudinally extending tongue yieldingly l connected between its end with thevjaw and springing at its rear end into engagement with the post when the jaw is closed,I substantially as set forth.

5. A clasp comprising a main plate, a post thereon, and a pivoted jaw whose body portion is provided with front and rear slits partially se arating therefrom a longitudinally exten in tongue yieldingly connected between its en s with the body of the jaw, substantially as set forth.
